Hi Luc, Hi Sébastien, as rightly pointed out by Christian, the bug reported in MATH-718 is in fact a result of the current implementation of the incomplete beta function I(x, a, b), which is inaccurate when a and/or b are large-ish. I think this is a very interesting issue, but also one

I completely agree with Simone. I see [graph] as the right place not only for well-known algorithms but also for state-of-the-art results, where graphs are either support structures for computation or actual main data structures fitting the user domain. P.S.: with this I am not saying that
